门站天然气计量测控系统改造设计及实现

Design and Realization about Measurement and Control System of Natural Gas in Gate Station

介绍了用计算机、RTU及工业以太网实现门站天然气计量测控自动化的方法。结合工程实际,详细阐述了改造一套天然气计量测控系统的系统设计、硬件选型、人机界面软件设计和RTU软硬件组态方法。具有投资小、工期短、计量精度高、结构简单、易于维护等特点,具有在天然气门站推广的前景。

In this paper , the method of realizing the automation of natural gas about measurement and control in gate station by computer, RTU and intranet are introduced. Integrated with practice, system design,hardware selection, HMI software design and RTU hardware and software configuration are described in detail. The system has the merit of low investment, short project time limit,high precision, simple structure and easy maintenance, which has the prospect of being widely used in gate station of natural gas.
